Answer:

x = -2

Step-by-step explanation:

The line represented in the graph is x = -2.

We know that lines in the form x = are vertical, and lines in the form y = are horizontal.

From this, the vertical line that intersects (-2,0) is x = -2.

Let f(x) = 2x + 5 and g(x) = x^2 - 3x + 2

denis-greek [22]

Answer:

The answer to your question is below

Step-by-step explanation:

f(x) = 2x + 5

To solve letter a, just multiply each term of f(x) by 3 and subtract 2.

a) 3f(x) - 2 = 3(2x + 5) - 2

= 6x + 15 - 2

= 6x + 13

To f(x) subtract twice g(x)

b) f(x) - 2g(x) = 2x + 5 - 2(x² - 3x + 2)

= 2x + 5 - 2x² + 6x - 4

= -2x² + 8x + 1

Multiply 5 by each term of f(x) and divide it by g(x)

c) $\frac{5f(x)}{g(x)} = \frac{5(2x + 5)}{x^{2} - 3x + 2}$

= $\frac{10x + 25}{x^{2}-3x + 2}$

Let be the density function for the shelf life of a brand of banana which lasts up to weeks. Time, , is measured in weeks and .

Maurinko [17]

The question is incomplete. The complete question is :

Let $p(t) = -0.0375t^2 + 0.225t$ be the density function for the shelf life of a brand of banana which lasts up to 4 weeks. Time, t, is measured in weeks and $0 \leq t \leq 4$ . Incorrect answer icon Your answer is incorrect. Find the mean shelf life of a banana using . Round your answer to one decimal place.

Answer:

2.4

Step-by-step explanation:

Given :

$p(t) = -0.0375t^2 + 0.225t$

Mean :

$=\int_0^4 tp (t) \ dt$

$=\int_0^4 t (0.0375 t^2 + 0.225t) \ dt$

$=-0.0375 \int_0^4 t^3 \ dt + 0.225 \int_0^4 t^2 \ dt$

$=-0.0375 \left[ \frac{t^4}{4} \right]^4_0 + 0.225 \left[ \frac{t^3}{3} \right]^4_0$

$=-0.0375 (64) + 0.225 \left( \frac{64}{3} \right)$

$=-2.5 + 4.8$

= 2.4

Therefore, the mean is 2.4

How do you do the math of 8 divided by 624

Veronika [31]

We can write it down as a fraction:

$\frac{8}{624}$

and we can simplify this fraction:

$\frac{8}{624}$
= $\frac{4}{312}$
= $\frac{2}{156}$
= $\frac{1}{78}$

or we can write it as a decimal:
0.1282...
